Gas Boiler Servicing in County Sligo

Gas boilers provide clean, efficient heating for homes connected to the natural gas network in and around Sligo Town. While gas is a convenient and cost-effective fuel, it requires proper maintenance and respect. A gas boiler that is not regularly serviced can develop faults that reduce efficiency, cause breakdowns at the worst possible time, and in the most serious cases, produce carbon monoxide - a silent, invisible killer. Annual gas boiler servicing by an RGI registered engineer is the best way to keep your household safe and your heating running at peak performance.

Our qualified engineers provide a comprehensive annual gas boiler service across the gas network areas of County Sligo. Every service includes a full inspection, burner cleaning, flue gas analysis, and testing of all safety controls, with a written report for your records.

Our Gas Boiler Service Process

A thorough gas boiler service follows a structured procedure that covers every critical component of the appliance. Here is what our RGI registered engineer does during your service:

Gas supply and pressure - We test the gas pressure at the meter and at the boiler inlet to verify the supply is within the safe operating range. Low or fluctuating gas pressure can cause the boiler to underperform or fail to ignite, while excessive pressure is a safety hazard.

Burner inspection and cleaning - The burner is inspected for damage, corrosion, and blockages. On many gas boilers, the burner can be lifted out for inspection. We clean any deposits and check that the flames burn evenly with the correct blue colour. A yellow or orange flame indicates incomplete combustion and potential carbon monoxide production.

Heat exchanger - We inspect the heat exchanger for cracks, corrosion, and blockages. A cracked heat exchanger can allow combustion gases (including CO) to mix with the heating water - a serious safety issue. We also check for soot deposits that reduce heat transfer efficiency.

Ignition system - The spark electrode or hot surface igniter is checked for wear and correct positioning. Faulty ignition is one of the most common causes of gas boiler lockouts.

Condensate system (condensing boilers) - Modern condensing boilers produce an acidic condensate that drains through a plastic pipe. We check this pipe is clear and correctly routed. Blocked condensate pipes are a very common cause of boiler failure during cold weather - the condensate freezes in the pipe and the boiler shuts down.

Flue gas analysis - Using a calibrated electronic analyser, we measure the CO, CO2, and flue gas temperature. These readings confirm whether the boiler is burning gas efficiently and safely. We record the readings on your service report and compare them to the manufacturer’s specifications.

Safety controls - We test every safety device on the boiler including the overheat thermostat, the pressure relief valve, the gas valve, and the fan proving switch. These devices are designed to shut the boiler down safely if a fault develops, and they must be in working order.

Why Gas Boiler Servicing Is Essential

Annual gas boiler servicing is about three things: safety, efficiency, and reliability. Each one matters to Sligo homeowners.

Safety first - Carbon monoxide poisoning kills people every year in Ireland. It is produced when gas does not burn completely, which can happen due to a blocked flue, a cracked heat exchanger, inadequate ventilation, or a poorly adjusted burner. You cannot see, smell, or taste carbon monoxide, so the only way to know your boiler is safe is to have it professionally checked. We strongly recommend fitting a CO alarm near your boiler as an additional safeguard.

Lower fuel bills - A gas boiler that has been properly serviced burns gas more efficiently, extracting the maximum amount of heat from every cubic metre of gas. Even a small reduction in efficiency - say 5 percent - adds up to a noticeable increase in your gas bills over the course of a heating season. Regular servicing keeps your boiler operating at its designed efficiency rating.

Fewer breakdowns - The majority of gas boiler breakdowns during winter are caused by issues that would have been identified and resolved during an annual service. A worn ignition electrode, a partially blocked condensate pipe, or a degraded gas valve seal might not cause an immediate failure, but they are ticking time bombs that will eventually let you down on the coldest night of the year.

Manufacturer warranty compliance - Gas boiler manufacturers universally require annual servicing by a qualified engineer as a condition of their warranty. Skip the service and you risk voiding your warranty, leaving you to cover the full cost of any parts or labour if something goes wrong.

When to Call a Professional

All work on gas boilers and gas appliances in Ireland must be carried out by an RGI registered engineer. This is a legal requirement, not just a recommendation. You should call us for a gas boiler service if:

• It has been 12 months or more since the last service - even if the boiler appears to be working normally
• You hear unusual noises from the boiler such as banging, whistling, or gurgling
• The boiler is showing error codes more frequently, even if it resets and continues running
• There is a smell of gas near the boiler - if you smell gas, open windows, do not use any electrical switches, leave the property, and call Gas Networks Ireland on 1800 20 50 50 immediately. Then call us to inspect and repair the appliance before it is used again.
• The pilot light keeps going out (older boilers with standing pilot lights)
• Your CO alarm has sounded - evacuate the property immediately and call the emergency services. Do not re-enter until the property has been declared safe.
• You are a landlord - landlords have a legal duty to maintain gas appliances in rental properties

Gas Boiler Servicing in Sligo

While the natural gas network in County Sligo is more limited than in larger urban centres, an increasing number of properties in Sligo Town and along the gas network extensions have gas-fired heating. As the network continues to develop, more households are converting from oil to gas for the convenience and often lower running costs.

Whether you have a Vaillant, Worcester Bosch, Baxi, Ideal, Potterton, or any other brand of gas boiler, our RGI registered engineers have the training and experience to service it to the manufacturer’s specifications. We are not tied to any single brand, so you get impartial, professional service regardless of what boiler you have.
